SPECIFICATION forming partbf Letters Patent No. 646,350, dated March 27, 1900. I

Application filed August 19, 1899. Serial No. 727,842. 1 (No modeL) To all whom it may concern:

Be it known that I, ANTON RICHARD BREINL, a subject of the Emperor of Austria-Hungary, residing at Graslitz, Bohemia, Austria-Hungary, have invented certain new and useful Improvements in Playing-Balls, of which the following is a full, clear, and exact descrip-v I ing of cotton or other fabric, over which for the purpose of keeping out water a thin impermeable skin or covering, of animal or other skin-for example, gold-beater skin--v is placed, the covering being then preferably coated with a varnishlike non-cracking layer of cellulose material or the like.

In the accompanying drawings, Figure 1 is a view of the filling mass. Fig. 2 shows the filling mass with the Wrapping of yarn.

is as follows: Waste pieces of sponge of the kind known as bath-sponge are not suitable in their original condition to be used as a filling mass for these playing-balls, as they are either too hard or too soft and in most cases are more or less filled with sand or other substances and do not possess suiii'cient. elas- Fi, 3 shows the ball after the covering of fabric,

purpose, on the one hand, of entirely kee ticity. In order to make this sponge elastic and suitable for ball-filling, it is exposed for some time to the action of steam and then immediately cooled with cold water. This operation makes the hard parts of the sponge soft and removes the impurities. The prodnot prepared in this manner is elastic and is excellently suitable as a springy material to be. used as the filling material for balls. In fact, it excels in consequence of its lightness and extreme elasticity that of all rubber balls hitherto used. The required amountof slponge prepared in this manner suitable for t e size of ball required is then chosen and is wound around with cotton yarn or other binding or fastening material until the approximate spherical shape of the ball is attained. This partlyformed ball is then pressed into a round shape ina suitable hand-press, until it has acquired the desired degree of elastic bounce. After this has been donethe ball is again wound-around until any portions of the sponge which may still project beyond the original meshes are completely covered and invisible. The next covering which is place over the ball is one of cotton or other fabric, for which parts of the well-known. tubular fabrics made on knittingmachines are particularly suitable,these parts being suitably cut out from these tubes and the free meshes of which are drawn together above and below in order to inclose the filling on all sides. By this means the ball as -snmes a uniformappearance and could in this condition be used as a ball in dry places.

,Inorder, however, tomake the balLSnjtable for any use andtomake it impermeable to water and moisture, the above-mentioned covering-of fabric is covered with a thin water and moisture tight skin, of animal on other nature, and isthenboated. with a rapidlydrying-coating' ofnon-cracking oil-color, celluloid or rubber mass, varnish, &c., for the ing outmoisture, and, on the other hand, of making the outerfippearance of the ball of a suitable color or appearance.
